What type of wings do Odonata have?
Both dragonflies and damselflies have two pairs of elongated membranous wings with a strong crossvein and many small veins that criss-cross in the wings, adding strength and flexibility to the wings. Both groups also have a characteristic nodus, or notch, in the front edge of each wing.
Do Odonata have wings?
The principal structural features of adult odonates reflect adaptations to flight. Adults have two pairs of narrow, typically transparent wings and a long, slender abdomen consisting of 10 segments. The head has prominent eyes and inconspicuous antennae, and the thorax is tilted along the body’s axis.
What is the wing structure of a dragonfly?
The wings of dragonflies are mainly composed of veins and membranes, a typical nanocomposite material. The veins and membranes have a complex design within the wing that give rise to whole-wing characteristics which result in dragonflies being supremely versatile, maneuverable fliers.
What is wing venation in insects?
Venation is the name given to the arrangement (number and position) of veins within an insect’s wing. Entomologists study the venation of wings and this is often used as a way of differentiating between otherwise similar species.
What are the sub orders of order Odonata?
Odonata was until recently composed of three suborders: Anisoptera, commonly known as dragonflies; Zygoptera, commonly known as damselflies; and Anisozyoptera, as the name denotes, a morphological composite of the previous two suborders.
How many wings do Orthoptera have?
two pairs
They have two pairs of wings, which are held overlapping the abdomen at rest. The forewings, or tegmina, are narrower than the hindwings and hardened at the base, while the hindwing is membranous, with straight veins and numerous cross-veins.
What are the lines on dragonfly wings?
The dainty veins gracing the wings of dragonflies and other insects are like fingerprints: Each wing displays a distinct pattern. A randomized mathematical process may help explain how certain thin filaments, called secondary veins, form these complex patterns, a new study finds.
Why do dragonfly wings have veins?
A dragonfly’s wings are made of a series of veins and lightweight membranes, which help make this insect more aerodynamic.
What are the types of wings in insects?
Types of Insect Wing
- Tegmina: e.g. Forewings of Grasshopper and Cockroach: Wings are leathery or parchment-like. They are protective in function.
- Elytra: e.g. Forewings of Beetles and Weevils: Wing is heavily sclerotized and thick.
- Hemelytra: e.g. Red Cotton Bug: The basal half of the wing is thick and leathery.
Does dragonfly have wings?
Wings: Two pairs. Both pairs are membranous, clear and similar in length. In dragonflies the hindwing is generally wider.
What kind of wings are in Orthoptera?
Orthoptera probably arose during the middle of the Carboniferous period. Most living members of this order are terrestrial herbivores with modified hind legs that are adapted for jumping. Slender, thickened front wings fold back over the abdomen to protect membranous, fan-shaped hind wings.
What kind of wings do the Orthoptera have?
They have two pairs of wings, which are held overlapping the abdomen at rest. The forewings, or tegmina, are narrower than the hindwings and hardened at the base, while the hindwing is membranous, with straight veins and numerous cross-veins. At rest, the hindwings are held folded fan-like under the forewings.

What are the Suborders of Odonata?
All Odonata have aquatic larvae called nymphs, and all of them, larvae and adults, are carnivorous. The adults can land, but rarely walk. Their legs are specialised for catching prey. They are almost entirely insectivorous….

What does a dragonfly wing look like?
Dragonflies have long, delicate, membranous wings which are transparent and some have light yellow coloring near the tips. Their bodies are long and slender and they have a short antennae.
